United People's Party (Singapore)

The United People's Party (abbreviation: UPP) was a political party in Singapore, formed by former People's Action Party (PAP) leader Ong Eng Guan. UPP was registered on 14 July 1961.

The party fielded 46 candidates to contest the 51 seats in the legislative assembly in the 1963 general election. Ong won the Hong Lim seat with 44.5% majority votes, that was lower than the over 70% he received during the 1959 election under the PAP, and 1961 election as an independent candidate.

Although UPP won one seat and became the opposition, the party's existence was in doubt as Singapore was ousted from the Malaysian federation by the Malaysian Prime Minister Tunku Abdul Rahman. In June 1965, Ong resigned from his seat, citing the lack of "effective media whereby opposition parties can convey their message to the people". The vacated seat was won back by the PAP in the by-election.

Subsequently, UPP became dormant, and did not contest in further general elections, although it remains registered as a political party.
